Mine Detonation Radius

Can someone please explain what exactly is mine detonation radius?
Does this add aoe to the mine detonation? or am I mistaken?

Traps have trigger raidus. That node concerns Traps AND Mine.

This node only applies the damage modification for the mine. A mine is always hand detonated I think.

Yes the mine is always hand detonated, so I am confused as to what this node does for mines...

anyone?

Im not sure on this one but I think it increases the radius of mines when targeting enemies (ie with fireball spell)

ahh I see, that would seem to make sense... cheers

Have this question ever been answered? I would like to know - rather than what 1 person probably think. Is it the normal range of a skill plus the percentage in the tree, or is it a fixed radius a mine has with the percentage increase from the tree, or is it a %aoe increase of the skill. This can make big difference to what skills are viable (if it is a fixed radius then mines are even worse than I assumed)

Still no answer on this one..not even in google or wiki.
GGG, please notice this question :-)

I've been searching the web for answers to this question, too. GGG, pls halp..
